Description
Technical field
The present invention relates to a kind of sterilizing installation, especially relate to a kind of high pressure steam sterilization equipment.
Background technology
Autoclave, can be divided into portable high-pressure sterilizing pot and vertical high-pressure sterilizing pot. Utilizing electric-heating-wire-heating water to produce steam, and maintain certain pressure, keeping the regular hour thus reaching to kill sterilizing article institute band all life body under the vapor (steam) temperature that this pressure is corresponding. Common autoclave mainly has a staving that can seal, Pressure gauge, air bleeding valve, relief valve, and heating wire etc. forms. Current high-pressure steam sterilizing pan mainly has full-automatic and plain edition. Full-automatic passes through microcomputer-recognized intelligent Automatic Control, controls sterilization pressure, temperature, time; Exceed design temperature, automatically cut off heating power supply; Intensification, sterilizing, steam discharge, dry run automatically control, and need not manually supervise. And plain edition high-pressure steam sterilizing pan indicates steam pressure by Pressure gauge, when pressure oversteps the extreme limit, relief valve automatically opens up aerofluxus blood pressure lowering, and relief valve can not be automatically switched off. Sterilizing need to maintain a period of time at the temperature corresponding to certain steam pressure, therefore sterilization process needs personnel to supervise in overall process, and regulates steam gas production by artificial Switching Power Supply and carries out Stress control. The most frequently used condition of autoclave has two kinds: 1. 103.4 kPas of vapour pressure temperature reach 121.3 DEG C, maintain 15-20 minute; 2. 67.6 kPas of steam pressure temperature reach 115 DEG C, maintain 30min. The mode of heating of high-pressure steam sterilizing pan is to be generated heat under certain voltage by heating wire, thus heating water to produce steam, owing to heating wire resistance is certain, therefore heating power square being directly proportional with voltage. Heating power can be regulated by regulating the mode of voltage. Full-automatic high-pressure steam autoclave is expensive makes its application surface be subject to certain restrictions, and ordinary high pressure steam autoclave is widely used because of low price.But ordinary high pressure steam autoclave is except relief valve no pressure actuator except blood pressure lowering under excess pressure, sterilization process can not effectively settle out when pressure is raised to sterilization pressure 103.4 kPas or 67.6 kPas, for making pressure be unlikely too high or too low, need operator to supervise and constantly turn off or on and off switch, use very inconvenient.
